Based on what I’ve learned from games like KSP and Spaceflight Simulator, anything in orbit will “roll” relative to the earth (ex if something is pointed away from
Earth at one point in orbit at the opposite point of its orbit it will point directly at Earth). Obviously a satellite would need to be always pointing toward earth, so how would it? I’ve also noticed this with the ISS when I watched a timelapse that was taken from the cupola.

In addition to the initial spin mentioned by the first comment, most satellites have small manuevering thrusters to keep themselves in the proper orbit and maintain their orientation, so these would be used as needed.
